Display device and displaying method thereof

Abstract

A display device is proposed. The display device includes a plurality of display panels. The display panels are stacked in sequence, and include a first display panel, a second display panel, a third display panel, a fourth display panel, a fifth display panel and a sixth display panel. The first display panel displays a first color; the second display panel displays a second color; the third display panel displays a third color; the fourth display panel displays a fourth color; the fifth display panel displays a fifth color; and the sixth display panel displays a sixth color. Each of the first color, the second color, the third color, the fourth color, the fifth color and the sixth color is one of blue, green and red. Two of the display panels display a same color. The display device switches to a two-dimensional display mode or a three-dimensional display mode. When the display device switches to the two-dimensional display mode, the two of the display panels display a same image. When the display device switches to the three-dimensional display mode, the two of the display panels display two images, respectively, and the two images are different from each other. Therefore, the present disclosure can present a three-dimensional visual experience without the need for the lenticular lens.
